Heating/plumbing Thermometers Combined thermometer/pressure gauges / thermo-hydrometers TM Pressure and temperature measurement with at a single measuring point With self-sealing connection thread for fast mounting Bottom connection or back connection With mounting valve for easy replacement without downtime Bottom connection version Application Description For liquid media which are not highly viscous, do not crystallise and do not attack copper alloys. For combined measurement of pressure and temperature, especially in heating systems and heating boilers. The combined thermometer/pressure gauge / thermo-hydrometer consists of a Bourdon tube measuring system for pressure measurement and a bimetal measuring system for simultaneous temperature measurement. Both values are measured and displayed by a single gauge. A self-closing mounting valve enables easy replacement of the gauge without the necessity to drain the system. An optional M 8 x to G¼ adapter is available if the combined thermometer/pressure gauge has to be mounted into an existing thermowell with M 8 x female thread.

Thermostats Control thermostats Temperature control thermostats TRT with capillary tube Mechanical temperature controllers For controlling and monitoring thermal processes Ideal for heat and process engineering Simple, robust design A Page 36 Application Description Mechanical temperature controller and limiter without external power supply. The device is suitable for application areas in the field of heat and process engineering. With the liquid-filled measuring systems and the short response times, the devices lend themselves for controlling thermal processes in appliance engineering, ovens, heating and air conditioning and other industrial or domestic applications. The temperature measured at the probe causes a change in the volume of the measuring liquid in the probe-capillary system. Electrical switching is triggered by the force acting. A thermowell allows for pressure-tight installation of the probe in various types of pressurised tanks.

Thermostats Safety temperature cut outs Safety temperature cut outs STB with capillary tube Ideal for heating and process industries For protection against exceeding the maximum temperature No external power supply Manual reset A Page 36 Application Description There are many application areas for safety temperature cut outs in the heating and process industries. In conventional oil or gas fired boilers, these devices are used to monitor the boiler water. The safety temperature cuts outs feature a manual reset button which must be actuated for unlocking. If the temperature at the probe increases, the measuring liquid in the measuring system expands. If the temperature exceeds a critical value, the device triggers, the voltage-free contact switches and the system is set to a defined safe state. When the temperature has decreased by approx. 5 K, the device can be unlocked and the system resumes operation.

Thermostats Surface mounting thermostats Surface mounting thermostats with housing GAT Mechanical temperature controller Ideal for underfloor heating systems Temperature limitation at pipes Easy installation with strap Application Description Surface mounting thermostat for strap mounting at pipes from 6 to 00 mm diameter. The version with internal adjustment and temperature control range up to 60 C is specially suited for underfloor heating systems. The surface mounting thermostat us a bimetal strip (element consisting of two metal strips with different heat expansion coefficients). When the temperature changes, the bimetal strip bends which triggers electrical switching.

Thermostats Immersion thermostats Immersion thermostats with housing GTT Mechanical temperature controller For controlling heating and cooling processes Ideal for heat and process engineering Control directly at the process Application Description Mechanical temperature controller and limiter. The device is suitable for application areas in the field of heat and process engineering. Heating and cooling processes in industrial or domestic applications can be controlled directly at the process. The temperature measured at the probe causes a change in the volume of the measuring liquid. Electrical switching is triggered by the force acting. The thermowell allows for direct installation pressure-tight tanks.

Thermostats With capillary tube Thermostats with housing GTK with capillary tube Mechanical temperature controller for remote measurement For controlling heating and cooling processes Ideal for heat and process engineering A Page 36 Application Description Mechanical temperature controller and limiter for remote measurement. The device is suitable for application areas in the field of heat and process engineering. Heating and cooling processes in industrial and domestic applications (in particular solar systems) are easy to control and monitor. The temperature measured at the probe causes a change in the volume of the measuring liquid in the probe-capillary system. Electrical switching is triggered by the force acting. A thermowell allows for pressure-tight installation of the probe in various types of pressurised tanks. Technical specifications Type GTK/TC2 Operating range 0/90 C Tolerance +3 K at ambient temperature 20 C Switching differential T 4 ± K Adjustment Externally adjustable Probe element Liquid-filled ø 6.5 x 95 mm Operating temperature range Probe: Max. 50 C : Max. 80 C Probe Copper Cable entry Plastic (PVC), grey (RAL 7040) M 20 x.5 Capillary length Cu capillary tube with PVC coating, black L =,000, 2,000 mm Degree of protection housing IP 40 (EN 60529) Time constant DIN-tested DIN EN 4597:202-09 Registration number TR/STB 2 Electrical switching contact Changeover contact Contact rating NC 0 (2.5) A 250 V AC NO 6 (2.5) A 250 V AC Plastic (PVC), grey (RAL 7035) Options Customised versions i See page 372 for prices. 366 www.afriso.de
